Abstract

A method for the production of continuous strip material from which bearing liners, thrust washers or the like may be formed comprises electro-depositing on a continuous steel backing strip an adherent coating of metal, e.g. copper, silver, capable of being wetted by the molten soft metal which forms the bearing surface layer, said coating extending up to or short of the edges of the packing strip so that said edges and the marginal parts of the strip are left uncoated, applying on the coated surface an evenly distributed layer of a soft bearing metal, e.g. lead. tin or babbit metal, which will not readily wet steel and heating the strip in a neutral or reducing atmosphere to melt the bearing metal and bond it to the coated surface of the backing. The uncoated steel edges and marginal parts of the strip confine the molten bearing metal to the coated surface and means for preventing the molten metal from flowing over the edges of the strip are not required. The coating may be electrodeposited on the steel backing and the coating removed from the edges and marginal parts by cutting means. The soft metal bearing surface may be of graded thickness transversely of the strip so that the marginal parts are thinner than the middle part to compensate for localised thickening of cut blanks when they are pressed into bearing liners. In an embodiment the strip is electro-plated with copper to a thickness of 0.0008 inch and the copper coating is removed along the edges of the strip to provide uncoated marginal parts of 1/8 inch wide. Lead is applied in the form of powder or thin strip or foil and the compound strip is passed through a furnace and heated in a neutral or reducing atmosphere to a temperature between 400 DEG C. and 700 DEG C. A lead alloy containing 12.5 per cent. antimony, 3 per cent. arsenic and 0.5 per cent. tin may be used.
